Description

The JIU Series of JetVent fans are suitable for car park installations where a low ceiling height and tight spaces make fitting the fans particularly challenging. The JIU CPC2 Series can be controlled either by a Variable Speed Drive (VSD) or a two-speed switching.

Features

Highly efficient, aerodynamically designed internal flow elements
Available with powerful 50 or 100N thrust capacities
Compact low profile design makes it suitable for applications with low ceiling heights
Durable galvanised steel housing with light grey powder coated finish as standard.
Integral mounting feet allows unit to be easily mounted to ceiling.
High/low speeds selected by switching from star to delta electrical connection.
Low noise/low speed models available.

Construction
Low profile galvanised steel housing with aerodynamically designed internal flow elements. Light grey powder coated finish as standard. Centrifugal or Mixed-flow impeller manufactured from durable aluminium. Electrical isolator fitted as standard.

Motors
Type - squirrel cage induction motor.
Electricity supply - 415V, three-phase, 50Hz.
Bearings - sealed-for-life, ball.
2-speed motor.
Speed control: Using 0 to 10 Vdc outputs to proportionally drive VSD or two speed system using relays to drive contactors.
Maximum ambient temperature 70°C

Internal Thermal Protection
Thermistors can be supplied on request.

Testing
Thrust-air performance based on tests to BS848 Part 10,1999
"Fans for general purpose - Performance testing of jet fans."
Noise data based on tests to BS848:Part 2,1985.

Special Note
Jet fans should be treated as an Alternative Solution within the National Construction Code (NCC)(formerly the BCA) from a fire and smoke control perspective (in addition to the ventilation requirements). Therefore the fire engineer on the project would need to add the car park ventilation design into their fire engineering report for the project and ensure that they meet the relevant BCA performance clauses. For more information please refer to the JetVent “Practical Guide for Selection and Application”

Special Features
There are two types of analogue control systems used with the JetVent JIU Series:

Two speed system using relays to drive contactors connected to the fans
Variable speed system using 0 to 10 Vdc outputs to proportionally drive VSDs

Suggested Specification

The high velocity jet fans shall be of the JetVent JIU Series as designed and manufactured by Fantech Pty Ltd and be of the model number shown. The housing shall be of galvanised steel with a light grey powder coated finish as standard. They shall incorporate mounting feet and aerodynamically designed internal flow elements. Impellers shall be of Mixed-flow or backward-curved centrifugal design manufactured from aluminium. They shall produce 50 or 100 Newtons of thrust and include a 2-speed star/delta motor.

Performance data shall be based on tests to BS848:Part 10,1999 for thrust and BS848:Part 2, 1985 for noise.
